Super Junior's Heechul shows off his friendship with BTS' Suga

Super Junior's Heechul took to his Instagram page to post a photo of himself and BTS' Suga on the set of 'Knowing Brothers'.

Before airing the BTS episode of 'Knowing Brothers', Heechul posted a selfie with himself and Suga. The caption reads, "My little brother Suga whom I met through 'Weekly Idol', it's already been 2 years since then...time goes by really fast. Before filming the first episode of 'Weekly Idol', I was told BTS would be appearing so I decided to look them up and while doing so, I became a fan ('Dope' MV was really dope and 'I NEED U' smashed my sensitivity). Also, I heard Suga and Heechul's chemistry was unreal today. You can check out the chemistry today through 'Knowing Brothers'."
